我在ubuntu服务器上，我一直在查找如何通过vnc连接本地vm以继续设置。 我使用
安装vmsudo virt-install --virt-type kvm --name debian-7 --ram 1024
--location=http://ftp.debian.org/debian/dists/wheezy/main/installer-amd64/
--disk path=/tmp/debian-7-amd64-vm.img,size=5 --network network=default
--graphics vnc,listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=debianwheezy --
extra-args="priority=critical interface=auto debian-installer/language=en
debian-installer/country=US debian-installer/locale=en_US keymap=us
preseed/url=http://public.thornelabs.net/debian-7-wheezy-preseed.seed"
我不知道我的问题是什么。当我尝试在显示器0上进入服务器vn时，我得到了相同的基本错误（我知道它在显示0上的事实）
Cannot open display
任何想法？一个人告诉我，我应该看看是否安装了虚拟磁盘。

快速而肮脏的黑客行为
